When evaluating solar panels, one key aspect to consider is their efficiency rating. The efficiency of a solar panel refers to how much sunlight it can convert into usable electricity. For 440W panels, the efficiency usually ranges between 20% to 22%, depending on the technology and quality of materials used. Higher efficiency translates to more power generated over a smaller area, which is particularly beneficial for locations with limited roof space.
